Harbor Freight Air Compressor Central Pneumatic 3 Gallon

Harbor Freight Air Compressor

This is the Harbor Freight central pneumatic 3-gallon oilless pancake style

air compressor they also sell this in a what they call a hot dog style

compressor which instead of being short and squat like this it’s taller but

narrower this is kind of wide the other one is narrower but taller to make up

for it it’s the same capacity same motor same everything else on it like I said

this is oilless or is it actually oils so apparently they can’t even spell

together right on the same thing because that’s the correct way obviously that’s

not but anyway you don’t want to buy an oil-less compressor unless you know what

you’re buying and in this case the item was cheap enough they were running their

quote-unquote sidewalk sale so I picked it up for 40 bucks and I don’t need it I

only got it because I have my big compressor and that’s working fine I

just got it because it’s handy to tote around and stuff like that sometimes

it’s just nicer for blowing out different things just a little one and

this is not going to run an impact gun it’s not going to run a paint sprayer

it’s not going to do any of that you can pump a tire up with it you can put a

little blow gun on it and blow dust out of computers or off of other items stuff

like that this is an item six oh six three seven I think they have two or

three other items that are exactly the same product just with a different item

number for some reason they do that again it’s three gallon hundred max

working psi which should be a hundred psi max working pressure if you wanted

to say back directly and 1/3 horsepower ones they’re running horsepower they

make it all weird and for the tech specs on it it’s point 6s FM and 90 psi and 1sc FM at 40 psi

and it’s got onboard accessory storage easy to read gauges and closed motor housing

with a handle and will take it out of the box in a second includes the Quick

Connect coupler that you see on the box there so let’s go ahead and take this

out of the box and take a look at it just a quick word on why you really

don’t want an oilless compressor if you can help it and their compressor has a piston that

moves up and down and just like in your car that has Pistons that move up and

down your car needs oil and oil changes without oil it will promptly seize up

and cost you thousands upon thousands if not an entire new vehicle in an oilless

design the lubrication is built into the unit and it’s permanently lubricated

usually through a sintered item sintered is basically a term that is the type of

metal what they do is they get filings of metal and compress that down into the

actual shape of what they need and oil is impregnated into that and it has a

very thin layer of lubrication and that’s what it has being that this is

not really a high volume high usage type air compressor that’s why they get away

with that but if you ever can help it when you’re buying a compressor buy one

that actually uses oil because it will last much much longer than one that is

oil is okay here we are unboxed and pretty much what you see is what you get


here it’s your basic three gallon oilless compressor pancake style like

that it’s got a little rubber feet on it a semi safety valve rated for there’s

actually a little bit probably from testing so that means it may actually work that would be nice

probably set to about 125 psi I haven’t read it so I’m guessing on that your psi of the

unit of the tank and your regulated pressure and your output now you will

need another device for this in order to make this work properly and I’ll get to

that in a moment on top here you have a little storage caddy for stuff maybe a

blowgun or something and your on/off switch and this particular item number

which was 606 37 is equipped with a fuse rather than a resettable circuit breaker

I’m not terribly thrilled with the fact that it’s a fuse I believe it’s a three

amp probably half inch long glass fuse on you can always replace it I don’t

plan on blowing the fuse of course but in the event it does blow my little old

Campo house fell of compressor I had years ago I had no protection of any

kind so I could probably just bypass that and be fine I don’t know for a fact

but I would expect that the motor in this unit would be thermally protected

so in the event it should overheat it should turn itself off to prevent it

from spontaneously combusting anyways we’re about ready to get going there’s a

little hang tag on it whatever but like I said you will need something and there

is a break-in period so I’ll show you how that works now okay so what you need

to do at this point is you need to run this with the regulator fully open to

allow maximum pressure out but you don’t want the tank to actually fill what they

say to do in the book is to run the unit totally open like that for a half hour

is a break-in period then you can shut it down and you know fill it up and actually

are using it and they say the way you’re supposed to do that is to use something

like this an air fitting I happen to need a whole bunch of these anyway so I

have it so I’m just going to put that in the port here like I said it comes with

the quick disconnect here but you will need something like that or you can just

cheat maybe not really the best way but you can just cheat and leave the drain

valve open and that way you won’t have to worry about that so I’m going to set

this up and we’re going to run this for a half hour to make a lot of noise and

once it’s done then we can actually see for the hole pressure okay we’re all set

for the break-in I have the fitting installed over here regulators fully

open ready to go it’s about 10 after 4 so we got to run this for half hour so

about 4:40 we’ll come back and shut it down and see how we did time for ignition

all right it is running we have airflow even let it do its thing

break-in and that’s that simple as that will eject this is now sealed off that’s open

I believe the drain valve is closed everything here has stayed remarkably

cool this is just barely warm the casing is barely barely warm so looks like it’s

pretty good so what we’re going to do next is we’re going to start it up and

see how long it takes they say about four minutes but I’m just going to put

the watt meter on it just so we have a visual idea of that okay watt meters in everything sealed up

let’s give this a shot we’ll see what this reads on and this will start up and

take note of what it reads initially when it starts and then when it’s really

in labor once it gets full right on that was less than four minutes

it went to close enough to 100 psi for China garbage but it started out like

what 181 and went to 230 or so something like that so only 50 watts difference

and even 230 watts is not a lot of electricity awesome we got a full tank

here we’ll test the safety valve I’ll just shut the switch and then I’ll turn

it back on and pump it up and then we’ll see how this all works here so let’s

just give this a shot here I just test the valve

okay resealed refire wait for that to refill, yeah okay I have a hose hooked up this

is one of those stretchy flex hoses and a blowgun this is just an old hose I had

laying around it’s discolored I don’t know why but it wasn’t that way when I

put it away so I have no idea anyway we’re back up almost at 100 I don’t

think that can be adjusted but maybe we’ll take a look maybe we won’t

I don’t know yet let’s just blast this and see when it when the cutting

pressure is and obviously you can continue using it you don’t have

I’m just waiting here to give you there we are now we’re just going to

blast this and give like if you were blowing something out or getting rid of

dust or something now you get a good few folks out of it before

now if you’re going to run something else especially from Harbor Freight like

the central pneumatic air screwdriver this is just a toy I wanted really it

works I haven’t really actually ever used it except just to make sure that it

runs and it does you’ll see that this is going to run this out of here pretty quick

so you see that’ll run they are quick but depending on what you’re doing in

have just enough or what so all in all this is actually a pretty

nice compressor and it seems to certainly work so it’s turned its keep I

guess you could say and we could take off these tags and remove the plastic

thing here on the on the gauges if it’s actually removable it’ll be really nice

if I could actually get it off of there there is more well I’ll have to play

with that later on because this there it is it’s being recalcitrant as usual and

that’s pretty much what it looks like so all in all a pretty good little

compressor like I said I was able to pick this up at their sidewalk sale or

whatever they call it for 40 bucks which was certainly a steal

even if 50 bucks which a lot of times they will have it on sale for is still a

very good price and if this is your first air compressor and again you know

why you’re buying an oilless compressor as I explained earlier in the video and

what you’re using it for very light duty work this would certainly be a decent

enough compressor to start with and once you find that three gallons isn’t enough

because ultimately you will then you’ll get a larger one and they have a six

gallon and then you can upgrade to you know bigger and better stuff of course

but certainly a great air compressor to start out looks easy enough to pop the

hood so let’s do that and see what makes this one go in pure Harbor Freight

goodness with the Harbor Freight screwdriver reviewed in a previous explanation

there are six screws you got four of these I only have two here because the

other two stayed behind they go here and here and in the back you will need a

screwdriver at least this long in order to take them out so there’s two back

here and the handle is held on by a much finer thread screw that you can see there just like

that once you do that remember make sure your power is disconnected and the

switch is off so because the maninjau I don’t need that safety third and off we go

and here’s what we find inside still with everything on and live I’m not

afraid of anything in here it’s only a hundred and twenty volts ain’t gonna hurt you

this is especially dangerous because if that does happen to start up it will

hurt this actually looks to be like a pretty decent unit considering based on

what my old one was and I don’t really have the parts anymore looks to be a

much larger motor which is quite warm but then again I have had it running a

bit this is the cylinder head right here and that is also hot because that’s

where the air goes and the air comes out and down into the tank down here right

here this thing is the pressure switch so it is not adjustable by any means it

just is what it is so it’s 100 psi you know obviously if you want to make this

thing blow itself up you just disconnect these wires and shorten and then

eventually the valve here will pop and that’ll be that but it’ll pump higher if

you need it to before blowing up fuse in line and the switch like I said if that

fuse ever blows just cut these two wires right here splice them together if you

don’t want to replace the fuse this motor has got to be thermally protected

and that’s really it that’s all it makes it tick here the output of course you

can take this apart a little further if you want you know the bolts here to

remove the motor and all that but there’s the fitting for the output from

the tank here under the spa the cover and that basically goes into

this manifold which has your regulator output pressure to your output and of

course the safety valve over here that’s pretty much all there is to it folks.
